LOUIS TAMPIER, OF BORDEAUX, FRANCE.

APPARATUS FOR DISPLAYING PUBLIC ANNOUNCEMENTS.-

SPECIFICATION forming part of Letters Patent No. 373,951, dated November 29, 1887.

Application filed April 22, 1887. Serial No. 235,756. (No model.) Patented in England June 10, 1886, No. 7,818.

To all whom, it may concern:

Be it known that I, LOUIS TAMPIER, at present residing at the Gons ulat General de Turquie,Bordeaux,inthe Republicof France,have invented new and useful Improvements in Apparatus for Exhibiting Public Announcements or Advertisements, (for which Letters Patent of Great Britain have heretofore been granted to me, dated June 10, 1886, N o. 7 ,818,) of which the following isa full, clear, and exact description.

This invention relates to apparatus for exhibiting series of public announcements or advertisements carried by a band which is caused totravel past an opening for the purpose of exhibiting the advertisements, 850., in succession; and the invention consists, essentially, of I mechanism whereby an intermittent or a continuous motion is imparted to the band, and

whereby such motion is automatically reversed at the required times, in order that the display of the announcements, &c., shall be continued uninterruptedly. This mechanism comprises rollers acting alternately as takeup and let-off rollers for theband and mechanism hereinafter described,whereby the direction of their motionis automatically reversed at the proper times in order to reverse the travel of the band. Two or more such bands may be exhibited in the same case and may receive similar or different motions.

Reference is to be had to the accompanying drawings, forming a part of this specification, which represent an apparatus comprising two bands, one receiving continuous and the other intermittent motion.

Figure l is a front elevation of the upper I portion of the mechanism, the front of the casand 3 "v are similar elevations of the opposite side, showing more clearly the holding and guide rollers and the position of the bands thereon, and also the driving mechanism for the continuously-moving band. Fig. 4. is a front view of the clockwork; and Figs. 5 and 5 6 are a vertical section on line 2 2 and a side elevation, respectively, of Fig. 4. Figs. 6 and 6 are detail side views of the ratchetwheel which is at intervals engaged with the ratchet-teeth on the periphery of the camwheel. Fig. 7 is a detail side view and section of the clutch for reversing the mechanism.

Fig. 8 is a detail side view of the chain-wheel for the intermittent band and of the device for controlling the said chain-wheel. Fig. 9 is an edge view of the same. Fig. 10 is a side view of the mechanism at one end of one ofthe winding-rollers. Fig. 11 is a cross-sectional viewv of Fig. 10. Fig. 12 is a side view of the mechanism at the other end of the said roller. Fig. 13 is a cross-sectional view ofthe same. Fig. 14: is a face view of the cam as laid down.

The same letters of reference indicate the same parts in all the figures.

The power by which the actuating mechanism of each band is driven is preferably a spring-barrel; but any other available prime mover may be employed.

A A are the two bands, receiving the one continuous and the other intermittent motion,

\ respectively. Their ends are attached to and wound on pairs of rollers a a a a respectively, the bands passing over intermediate gniderollergand the portions of the bands distended between the guide-rollers being exhibited at openings at in the case within which the mechanism is contained. Certain of the guide-rollers act also as driving-rollers for the bands, and for this purpose they receive a positive motion.

B B are the endless chains by which the two sets of rollers forthe bands A A are respectively actuated.

O is the driving mechanism for the band A, and (3 the mechanism for the band A The band A, attached to and wound on rollers a a, as above described, passes over or round guide-rollers d 6f, as shown in Fig. 3,

whereof the roller f receives motion from the clock-work O and'transmits it through endless 10o chain B to the rollers a a. This rollerf is roughened at the middle in order that it may assist in driving the band, which is pressed against the roughened part by a soft roller, 9, carried by a spring.

The clock-work 0 consists of a spring-barrel and train of wheels and pinions controlled by a fly, h, the wheeli of the train being in gear with the pinion f, fastened on the end of the roller f.

Upon the shaft of wheel i are two loose pinions, 7: Z, in gear with the wheel on on the second-motion shaft, the one 7; gearing directly therewith and the other, Z, gearing indirectly through pinions m n on a counter-shaft, 0. Between these piniousk Z the shaft of the wheel iis squared, and carries a clutclnp, formed of arms carrying pins 1), one or other of which comes into the path of an arm, is or Z, fixed to the pinions is Z, whereby the shaft of wheel 1' is rotated in one or other direction, as the case may be. The clutch p is slid along the shaft to throw it into gear with one or other of the pinions kl and produce the desired reversal of motion by a cam, q, (whose development is shown in Fig. 14,) acting on the pin a of a sliding rod, 8, carrying a fork, s, embracing the grooved boss of the clutch. The cam has a ratchet-toothed periphery, q", and is driven by a ratchet-pinion, q, (shown more clearly in Figs. 6 and 6,) on the second-motion shaft q", the object of this form of gear being to permit of the position of the cam being adjusted to suit the position of the band, which is done when the pinion is in such position that its teeth do not gear with the teeth on the cam, as shown in Fig. 6". The chain B runs on a chain-wheel, 1), fast on the other end of roller f, and gears with similar chain-wheels, c, on

the axles of rollers a.

w z, &c., are guide-wheels. Each wheel 0 (see Figs. 11, 12, and 13) runs loose between collars on the boss of a ratchet-wheel, f, with which engages a pawl, 0, carried by the wheel 0. The ratehets are made friction-tight on the axle of the roller a by a spiral spring, a, compressed between the end of the roller a and the boss of the ratchet-wheel t, which is held in position by a cross-pin. At the opposite end of each roller is another ratchet-wheel, y, made friction-tight byaspiral spring, 7 compressed between it and the end of the roller, a pawl, y, mounted on astationary support engaging with the ratchet-wheel 3 The parts of the clock-work G, which are similar to those of clock-work O, are distinguished by the same letters, with the addition of an asterisk, and need not be again described. The wheel i is, however, in this instance, a ehain-wheel, and drives the chain B and the action of the clock-work C is controlled by an escapement actuated by the clock work 0 through a shaft, 2;, Fig. 4, which is rocked periodically by a ratehet-toothed pin, 22, on the second-motion shaft of clock-work O acting on an arm, v, fixed to the shaft. The eseapement consists of a spring-catch, w, Figs. 8 and 9,

pivoted to an arm, w, fixed to shaft 11, and engaging with a pin, 10*, fixed to wheel i and of a second catch, so, which comes in the path of the fly h", Fig. 2. By the motion of shaft 1) the catch to is first removed from the path of pin 10 the catch at, Fig. 2, meanwhile standing in the path of the fly M. hen the arm 1; falls off the point of a tooth of pinion v, the catch or is withdrawn also at the same time that catch w again comes in the path of pin w, whereby the elock-work C is permitted to run until the wheel t" has made one revolution, when it is again arrested. The chain B gears with ehain-wheelsc, connected with the axles of rollers a by ratchet and friction gear similar to that before described. The chain also gears with a pinion fast on the end of the roller f", which is in this instance the upper guideroller of the band. The roller a, which is for the time being acting as the take-up roller for the band, is driven through the ratchet and friction gear at the driving end of said roller, the gear at the other end thereof then being inoperative, and the necessary tension is applied to the band by the ratchet and friction gear at the opposite end of the other roller a (the let-01f roller for the time being) acting as a brake for the said roller, the gear at the driving end of the last-mentioned roller being then inoperative, and conversely when the direction of motion of the band is changed.

The object of using friction-gear between the drivingchain wheels and the rollers a is to prevent overwinding of the band and compensate for the varying diameter on which the band is wound.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is-- 1. In an apparatus for exhibiting public announcements, the combination, with a band secured to rollers, of a motor and a drivingchain for rotating said rollers from the motor, a sliding bar in the motor-frame, a cam driven by the motor operating said bar, a double sliding clutch operated from said sliding bar, projections on said clutch, pinions provided with arms with which the projections on the clutch can engage, and gearing for transmitting motion from said pinions to the wheels operating the driving-chain, substantially as set forth.

2. In an apparatus for exhibiting public announcements, the combination, with rollers, of a band secured at its ends to the rollers, ratchet-wheels on the rollers, toothed wheels mounted loosely on the shafts of the rollers, over which to the wheels the driving-chain passes, spring-pawls on the toothed wheels and engaging with the ratchet-wheels on the shafts of the rollers, and spiral springs surrounding the shafts and holding the ratchet wheels friction-tight on the axles of the rollers, substantially as set forth.

3. The combination, with a rollerand a band having one of its ends secured to the same, of

a ratchet-wheel mounted on each end axle of the roller and held friction-tight on said axles by spiral springs surrounding the axles, a toothed wheel mounted loosely on the post of the ratchet-wheel at one end of the roller, a driving-chain passing around said toothed wheel, a spring-bolt on said toothed wheel engaging with the ratchet-wheel, on the post of which the toothed wheel is mounted, and a fixed pawl engaging with the ratchet-wheel at the opposite end of the roller, substantially as set forth.

4. In an apparatus for exhibiting public announceinents, the combination, with two mo tors, of two bands, each secured at its ends to separate rollers, power-transmitting gear for driving the two sets of rollers separately from two motors, a flier on each motor, and a lever controlled from one motor and adapted to engage a pin on a wheel of the other motor, substantially as set forth.

5. In an apparatus for exhibiting public announcements, the combination, with two motors, of'two bands, each secured at its ends to separate rollers, power-transmitting gear for driving the two sets of rollers separately from two motors, a fiier on each motor, a lever controlled by one motor and adapted to engage a pin on a wheel of the other motor, and a rod connected with said lever and adapted to en- LOUIS TAMPIER.
